摘　　要：应用放射性核素心血管显像原理，一次性注药，同时获得放射性核素心血管造影及门电路心血池显像，测右心射血分数，肺尖、肺底放射性核素分布峰值，来定量分析肺动脉压力。结果，肺心病患者右心射血分数明显降低；肺尖与肺底放射性核素分布峰值比和右心射血分数之间呈负相关；而上述峰值比与应用心导管法测平均肺动脉压力呈正相关；平均肺动脉压与ＲＶＥＦ之间为负相关，该法简便，安全、重复性好，是一项无创性估价肺动脉压力的方法。epending on the principle of radionuclide angiocardiography ,we can obtain two images with druginjected once only:radionuclide angiocardiogram and gated cardiac blood pool.A quantitative analysis ofPAP was conducted by determining radionuclide peak of top-bottom of lung and RVEF. The resultshowed as follows:it was lower in RVEF of PHD group.It showed negative relation between ratio ofradionuclide peak of top-bottom of lung and RVEF(r=-0.75),but negative between the ratioand PAP(r=0.95).There was also negative relation between PAP and RVEF(r=-0.70).This method is simple,safe,repeti tive,sensitive and noninvasive for measur-ing PAP.
